INVENTOR LAL BEHAR ROY HOT WATER LINE COLD WATER/l L LINE United States Patent G 3,346,884 BATH TUB Lal Behari Roy, 4 Pusa Road, New Delhi 5, India Filed July 10, 1964, Sel'. No. 381,868 3 Claims. (Cl. 4-173) This invention relates to a bathing device such as a bath tub and has for its principal object to propose such a -construction that the bath water is relieved of the floating oily and frothy body washings as soon as such waste substances separate from the bathers body.

It is further the object of this invention that it should be possible to automatically remove the oily deposit from the bath tub, thereby saving the trouble of cleaning the bath ltub after each bath.

It is further the object of this invention that it should be possible to regulate the temperature of the bath water in course of the actual bathing operation.

According to this invention the bath tub comprises a hollow outer-shell open at the top, a bath tub with outwardly turned and rounded edges placed inside the outershell and having a clearance -between the bath tub and the outer-shell on all sides and the bottom of the bath tub, and a superimposed top resting secu-rely on the edges of the outer-shell with the lower part falling in line with the walls of the bath tub, having symmetrical outwardly turned rounded edges like those of the bath tub, but leaving all round clearance (gap) between the edges of the superimposed top and the bath tub.

Thus, in a-ccordance with one embodiment, the bathing device comprises a hollow outer-shell, bigger than the bath tub in all dimensions and having a drain-out pipe at the lower end of the sloping bottom, a bath tub having resting props under the outside bottom and placed inside the hollow outer-shell, and a superimposed top resting at the upper end on the edge of the hollow outershell and projecting inward horizontally for a few inches on all sides and then projecting downward, keeping in line with the walls of the bath tub.

The outer-shell has a sloping bottom with a drain-off pipe near the lower 'bottom end to be connected with the drainage system of the building.

The bath tub has la sloping bottom with an outlet pipe projecting downward and ending just above the drain-out pipe of the outer-shell; near the four corners and a few inches above the bottom of the bath tub are fitted four eyelets on the walls of the bath tub; in each eyelet there are fitted two jets which are connected by two separate pipes through two separate faucets with the cold-water and hot-water mains.

The faucet, connected with the hot water main, has one inlet and four outlets and is of such construction that, by operating the valve of the faucet, all the four outlets can be opened or closed simultaneously.

The faucet, connected with the cold water main, is of similar construction as the hot water faucet and operates in the same manner.

The faucets are placed at such a place on or near the bathing device that the bather can easily operate them from inside the bath tub and regulate the fiow of the hot and cold water in the bath tub at will at the time of the actual bathing operation.

The outlet pipe of the bath tub is fitted to the bath tub by a socket which has a stopper that is used for closing or opening the socket of the bath tub as and when desired.

The bath tub has two main faucets for hot and cold water fixed on the shorter wall and above the outlet pipe; these faucets are connected to the hot and cold water mains by pipes.

When the superimposed top is secured to the outershell, the bath tub is enclosed within the outer-shell and the bathing device gives the appearance of a single piece.

The bath tub and the superimposed top are both removable from the outer-shell by disjoining the hot and cold water pipes, so that the inner side of the outer-shell can be cleaned and refitted or the pipes and other fittings may be changed when necessary.

The outer-shell, the bath tub and the superimposed top are all made of sheet metal with the inner sides of the three pieces having highly polished and non-corroding surfaces; the outer surfaces are protected by decorative and rust resisting paints or enamels.

It is obvious that other -modiiications can be made within the ambit and scope of my invention,

The invention will now be more fully described with reference to the accompanying drawing in which- FIGURE 1 is a vertical section of the bathing device,

FIGURE lA shows the transverse sectional View of the bathing device,

FIGURE 2 is a somewhat schematic representation showing the position of the faucets and 'pipe connections to the eyelets,

FIGURE 3 is a schematic sectional view showing the positioning of the hot and cold water jets.

Referring to the drawings, 1 is the outer-shell holding the bath tub 2 in its hold with free space all round be- -tween the two to allow free flow of water spilling from the bath tub into the outer-shell, 3 is the water out-let pipe of the outer-shell. 4 shows the position of the eyelets four in number (two are shown and two are not shown) fitted near the four bottom corners of the bath tub and 5 and 6 show the alignments of the cold and hot water pipes for continuous supply of cold and hot water in the bath tub at the time of actual bathing operation. 7 shows the props on which Vthe bath tub stands inside the outer-shell, and 9 shows the stopper for` closing the outlet of the bath tub. 10 and 11 show the positions of the cold and hot water faucets meant for rapid filling of the bath tub with water of desired temperature before actual bathing operation. 12 shows the superimposed top which fits securely on the edges of the outer-shell and falling in line with the bath tub. 13 and 14 show the bent ends of the bath tub and the superimposed top and they are meant for allowing the floating body washings and oily matters to spill over into the outer-shell and keeping thereby the walls of the bath tub clean. 15 shows the all round gap between the edges of the bath tub and the superimposed top for allowing free spilling of bath water from all sides of the bath tub into the outer-shell. 16 and 17 shows the positions of cold and hot water jets fitted into the eyelets. 18 and 19 show the cold and hot water faucets regulating flow of cold and hot water into the bath tub through the jets fitted into the eyelets.

Referring to the functioning of the bathing device, when the bather fills the bath tub by opening faucets 10 and 11, the water level in the bath tub can rise maximum to the level of the gap 15. The faucets 10 and 11 are closed when the water level in the bath tub is a little below the gap 15.

The bather now enters the bath tub. Some water spills through gap 15 into the outer-shell 1 and drains out through outlet pipe 3. As shown best in FIGURE 1A, bath tub 2 is oval shaped in transverse section and (see FIGURE l) the end walls slope inwardly. Hence, the-re is no fiat bottom to which the water tends to cling, and it flows downwardly and washes the entrained materials with it to the outlet pipe 3.

The bather now opens the cold water faucet 18 and cold water fiows continuously into the bath tub 2 through the four cold-water jets 16 fitted in four eyelets 4. Consequently, water starts spilling through the gap 15 from the bath tub into the outer-shell resulting in drop of temperature of the water in the bath tub,

The bather now operates hot water faucet 19 in such` a manner that the requisite amount of hot water ows into the bath tub 2 through jets 17 to raise, -maintain or lower the temperature of the water in the bath tub 2 as desired by the bather himself in course of the bathing operation.

In the course of the bathing operation, frothy and oily body Washings oat on the surface of the lbath water and as the bath Water is continuously spilling over the gap 15, these oily and frothy floating matters also spill over gap 15 along with the bath water, keeping the walls of the bath tub .and the bath water inthe bath tub clean.

Thus, by proper manipulation of faucet 19, it is possible to increase, maintain or decrease at will the temperature of the bath water during the bathing operation and keep the bath water clean.
